Yea! Whole Foods now sells their own 365 branded Electrolyte Enhanced Water. It's just plain simple water loaded with electrolytes. Working out hard depletes your body of electrolytes and can lead you to dehydration if you don't replenish. Electrolyte replenishment is good too if you've been having a lot of diarrhea, vomiting, or haven't been eating enough.
About three years ago I wondered why there weren't more companies selling just plain water infused with electrolytes. Vitamin Water was pretty much the only game in town, and my marketing mind figured that someone else would come in with something similar yet cheaper and without any artificial ingredients.
In general, I don't care for most sport drinks because many are loaded with sugar, high fructose corn syrup or artificial sweeteners. To me, it kind of defeats the purpose of being vibrantly healthy by drinking something that has ingredients that are both helpful and not-so-helpful. There are so many choices for us so pick from so choose one that gives you the highest overall benefit.
